Abstract:
This study investigates the impact of responsible leadership on sustainable organizational
performance with the mediating effect of sustainable Human Resource Management
(HP.M) within Sri Lanka's apparel industry specifically in the Rathnapura District.
Drawing from stakeholder theory and sustainable HRM frameworks, the research explores
how responsible leadership practices influence long-term organizational sustainability
outcomes while emphasizing the role of sustainable HRM as an intermediary. Using a
quantitative research method, data were collected from 338 employees across two major
apparel firms through structured questionnaires. The findings reveal a positive and
significant relationship between responsible leadership, sustainable HRM, and sustainable
organizational performance. Furthermore, sustainable HRM was icientified as a key
mediating factor strengthening the link between leadership and organizational outcomes.
This study contributes to filling the empirical gap in leadership and sustainability research
in developing country contexts and provides actionable insights for industry leaders and
HR professionals aiming to align organizaiional practices with global sustainability goals.
